I have attached to multiple devices films and have it eigenltich also always good job. But in this film a lot of air bubbles are retarded. Even after a few days they have not regressed. The Tablet S has also been thoroughly cleaned with a lens cloth and the film was attached by means of a credit card. She then sat really fit, but at the bottom it has caught on after a few minutes to replace. Then I had to again attach scratch the film. By re-attaching a number of scratches have already emerged, although I have worked carefully. That you then what happens when you want to save money. So it's better to buy a more expensive film.
